Wind, Solar and Motion are usually unregulated energy sources. To regulate battery charging, control units are used :

Depending on the source, there will be charge regulation to keep the batteries charged and healthy. Another function of these control units is the load ie. how far you may safely discharge the battery.

Use the energy from the Battery direct or use an inverter to convert the Energy into electricity:

Depending on the purpose you could use the Battery direct in applications like Lighting, Security and Networking. There are TV's Fridge's and many more appliances which can run off Batteries. All that is required is an energy source, a controller and batteries. If AC 220V is required than you would simply use an inverter. If you don't have an energy source, a charger would be used to maintain the batteries.

Small investment with a fast payback:

Harvesting the sun to heat up water is another way of benefiting from free energy with a relatively small investment .

Typically the Solar Water Heater pays for it self in less than five years and continues to operate for many more. We stock high Quality Solar water heaters that have been performing for than 8 years (1999 indirect system ). The example on the left demonstrates a basic direct thermo siphon system. We have four different methods of heating water, contact us to help you choose the one that is most suited to your needs.

Cold Water enters through a Inlet (5) into an Insulated Storage Tank (2). From there it flows through a Panel (4) which absorbs Solar Radiation (3). The Solar Energy is absorbed as heat and the hot water re-enters the tank where is exchanges heat with the rest of the water through Convection or a heat exchanger. Hot water exits the tank at the top where it is used (1). The temperature at the top of the tank is warmer than that at the bottom because of Convection

Sounds like a great alternative?

Well almost, it takes energy to make Hydrogen and once its bottled it is highly flammable once mixed with oxygen. At WSM we only use hydrogen as a fuel for a fuel cell reactor which produces energy to charge Batteries.

We are continually looking for new improved technologies that use Hydrogen and will increase our Hydrogen gas offers in time.

Major power anyone?

This is another great idea which produces lost of Energy around the Globe. In South Africa we aprently have to digg to deep to make this a financially viable project. Well its clean, free and has a minor impact on the environment compared to Hydro power. But until we know exactly how far to digg, until we hit hot rock, to make steam, to drive turbines which will generate Giga Watts we will have to shelf this one.

High Quality air, Hot in winter , Cold in Summer?

There are many options in this regard, as always if you know what you want the outcome to be, then getting there becomes easier. So whether you need to extract air, heat, cool or improve the quality of the air you breathe, contact us.

We also have heating and cooling solutions for Pools and Spa baths.

Got something moving?

The Diagran on the left is an sterling engine which uses heat trasfere to move a piston.

At WSMP we use any motion to pump, grind or drive altenators to convert motion to AC or DC current. We can deploy bio fuel and gas combustion engingine generators that produce electricity,this can be interated into a single sytem using Solar, Wind and Hydro.

So contact us if you need to pump or generate, we stock Wind turbines and Hydro turbines perfect for small water power generation.

Gas vs the Sun?

Not everyone makes there own bio gas or has a gas line, the alternative is a Solar cooker. There are limitations and may require several small adjustments during the cooking process. We love it on the beach for a spit or potjie. Have a look at some recipes and general use recommendations: http://solarcooking.wikia.com/wiki/Recipes
